HistoStitcher is a free software package developed for reconstruction of whole mount histology sections (WHMS) from digitized tissue fragments. HistoStitcher allows users to select common fiducials on the edges of adjacent histology fragments and automatically determines the optimal transformations required to combine the images such that the selected points are maximally aligned. HistoStitcher also offers real time rendering of digital pathology images using multi-resolution pyramid to facilitate selection of fiducials, annotations of regions of interest and evaluation of the final stitch. This software is intended for research purposes only, not for diagnostic or clinical use. 



(1) Data conversion tool to convert images to tile-based multi-resolution JPEG-encoded image format (db)

(2) Stitching via fiducial selection 

(3) Manual image alignment without fiducial selection 

(4) Importing, exporting, viewing, generating and stitching annotations corresponding to histologic fragments of interest 

(5) Simultaneous viewing up to four high resolution, very large histologic images

AutoStitcher is a free software program developed for reconstruction of whole mount histology sections (WHMS) from digitized tissue fragments. AutoStitcher takes as input a set of 4 digitized histology quadrants. This software is intended for research purposes only, not for diagnostic or clinical use. 

For an example and instructions explaining how to run AutoStitcher, refer to documentation in the files AutoStitcher_example_script.m, and AutoStitcher.m.

HistoView is a graphical user interface for pathology image analysis and visualization. It supports whole-slide images, provides a variety of automatic segmentation algorithms based on CCIPD’s literature and technical description of existing medical image analysis algorithms, and visualization of the segmentation result.

In HistoView v1.0, color deconvolution algorithm is embedded, which separates the image into different channels, corresponding to the actual colors of the stain used. User can change a threshold from 0 – 100 to binarize the channel image to measure specific tissues or structures.
